並列摘要

A molecular dynamics (MD) study of thin film formation was performed to understand the adsorption phenomena of Cu nanoparticles on Ag substrate using the EAM potential. The purpose of the present study was to investigate the effects of twin interfaces on surface adsorption for thin film formation. The (110) substrate with higher surface energy shows higher adsorption as compared to the (111) substrate which has the lowest surface energy. To investigate the adsorption of Cu nanoparticles the atomic radial distribution function, spreading index, and coalescence index were calculated. The results indicate that the presence of a twin in the substrate significantly increases the adsorption process. The adsorption phenomena were found to be highly temperature dependent. The adsorption was slightly higher when the nanoparticles were exactly on both sides of the twin interface (BSTI) as compared to being on the twin interface (OTI).
